For example, a portable electronic device, such as a smartphone, a tablet PC, or the like, may support various functions such as access to Internet, playback of multimedia content as well as voice and message communication functions.

For the purpose of receiving the content or service desired by the user, the user of an electronic device needs to transmit the search keyword to the search engine. In the search using the search keyword as described above, it is inconvenient for the user to create the appropriate search keyword directly.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

SUMMARY

A dialog content providing service based on natural language understanding is being tried to overcome the inconvenience. The dialog content providing service may analyze the semantics of a user's natural language request to provide appropriate content to the user in a dialogue format.

A dialog content providing service can be provided through a rich communication service (RCS). The mobile network operator (MNO) may provide a user with the dialog content providing service using the RCS through the message application installed in the terminal, without an additional subscription procedure. The dialog content providing service may be implemented based on the message application providing a dialog user interface (UI). Typically, over the top (OTT)-based message applications have been developed by a number of developers, and the OTT-based message applications may be provided worldwide.

Conventional RCS systems may transmit and/or receive messages using a session initiation protocol (SIP). The RCS system may represent the address of the other party transmitting and/or receiving messages in the form of uniform resource identifier (URI) or uniform resource locator (URL). However, message applications, for example, a short message service (SMS), need a phone number to deliver the message to the other party of the conversation. In the case where the dialog content providing service is provided through RCS Infra, the phone number may not be immediately available. On the other hand, chatbots are typically addressed by using URIs or URLs.

Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide an electronic device, a server, and a method for providing a service using a telephone number such that a user is capable of conveniently accessing the service providing dialog content.

DETAILED DESCRIPTION

Hereinafter, various embodiments of the present disclosure will be described with reference to accompanying drawings. However, those of ordinary skill in the art will recognize that modification, equivalent, and/or alternative on the various embodiments described herein can be variously made without departing from the scope and spirit of the present disclosure.

FIG. 1A illustrates a dialog content providing system, according to an embodiment. In certain embodiments, the dialog content providing system permits an electronic device 100 to access a chatbot using a first communication protocol. In certain embodiments, the first communication protocol can be Rich Communication Suite (RCS) message. A platform server 200 provides a searchable registry of different chatbots 300. The registry associates a destination according to the first protocol for each chatbot 300. For example, the destination can be a Bot ID or a MSISDN. The electronic device 100 can access a chatbot 300 using the destination for communicating using the first communication protocol. The platform server 200 uses the destination to determine the identity of the chatbot 300. Additionally, the platform server 200 additionally converts messages from a first protocol to a second protocol used by the chatbot 300. The second protocol can be, for example, Hypertext Transmission Protocol (HTTP).

Referring to FIG. 1A, a dialog content providing system 1000 according to an embodiment may include an electronic device 100, a platform server 200, and content provider (CP) servers 310, 320, and 330 (collectively referred to as “300”). The electronic device 100, the platform server 200, and the CP servers 300 may be connected through, for example, data network (an example of a second network) (e.g., IP network or Internet).

The electronic device 100 may include at least one of, but not limited to, a portable communication device (e.g., smartphone), a computer device (e.g., a personal digital assistant (PDA), a tablet PC, a laptop PC, or a desktop PC), a portable multimedia device (e.g., e-book reader or MP3 player), or a wearable device. The electronic device 100 provides a user interface, wherein the user can select a chatbot from a plurality of chatbots. The electronic device 100 transmits a first connection request including a first phone number and a first identifier (ID) associated with the chatbot that the user selects to the platform server 200. The electronic device 100 receives a first connection response including the first phone number and the first ID from the platform server 200.

According to an embodiment, the electronic device 100 may access the platform server 200 through a data network (e.g., IP network or Internet) and may connect to a web page operated by the platform server 200 (so-called chatbot store) or may execute an application (chatbot store application). The user may search for the CP server 300 providing the desired service through the web page or the application, and may subscribe to the found CP server 300. The application may be a dedicated application. A bot service may be used to search for the appropriate CP server 300.

According to an embodiment, the electronic device 100 may communicate with the platform server 200 over an RCS network and may transmit and/or receive messages to and/or from the CP server 300 via the platform server 200. The message format between the electronic device 100 and the platform server 200 may be different than the message format between the platform server 200 and the CP servers 300. Accordingly, the platform server 200 converts the message format from the format between the electronic device 100 and the platform server 200 to the format between the platform server 200 and the CP server 300, and vice versa.

For example, the electronic device 100 may have a subscription to the first CP server 310. The electronic device 100 and the first CP server 310 may initiate a chat thread provided in the message application, based on the subscription. The message application according to an embodiment may be a native message application. When the chat thread is initiated, the electronic device 100 and the first CP server 310 may transmit and/or receive messages through the graphic user interface (GUI) (e.g., chatroom) provided by the native message application. For example, messages generated by the first CP server 310 may be transmitted to the electronic device 100 over an RCS network 10.

According to an embodiment, the format of the message generated by the electronic device 100 may be different from the format of the message generated by the platform server 200, or may comply with other protocols.

The platform server 200 may operate as a platform of the CP servers 300 and may relay messages between the CP servers 300 and the electronic device 100. For example, the platform server 200 may allow the electronic device 100 to search for the CP servers 300 or to transmit and/or receive messages between the CP servers 300 and the electronic device 100. The platform server 200 may serve as a conference focus. The platform server 200 may maintain and manage the connection of an SIP signal with the participants of a conference, and may perform the function of a conference server.

According to an embodiment, the platform server 200 may communicate with the CP servers 300 over a data network, and the platform server 200 may communicate with the electronic device 100 through the RCS network 10. Since the messaging format over the data network and the RCS network 10 are different, the platform server 200 may change the message format between the CP server 300 and the electronic device 100 through the RCS network 10. The format of the message generated by the CP servers 300 may be converted to the format of a message based on the RCS network 10, by the platform server 200. On the other hand, after being converted to the message of format based on the data network by the platform server 200, the message based on the RCS network 10, which is generated by the electronic device 100, may be transmitted to the CP servers 300.

According to an embodiment, the platform server 200 may include an RCS agent 210, a bot registry 220, and/or a bot service 230. As will be described in more detail below, the RCS agent 210 receives and transmits RCS formatted messages. The bot registry 220 stores the identity of each of the CP servers 310, 320, 330. The bot registry 220 can list the identity of each of the CP servers 310, 320, 330 with at least MSISDNs or phone numbers. Upon receipt of a phone number and identifier, the bot registry 220 can establish a connection with the identified CP server 310, 320, 330. The bot service 230 transmits and receives message from the identified CP server 310, 320, 330. The messages are forwarded to and from the electronic device 100 using the RCS agent 210. The configuration of the platform server 200 illustrated in FIG. 1A may be implemented with software and/or hardware. In addition, components of the platform server 200 of FIG. 1A may be respectively implemented in different devices or may be implemented in one device.

According to an embodiment, the RCS agent 210 serves as the interface between the electronic device 100 and the server 200. The RCS agent 210 may exchange messages with the electronic device 100 by using the RCS network 10. The RCS agent 210 may allow the electronic device 100 to receive dialog content by using the RCS network 10. For the purpose of transmitting a message from the electronic device 100 to the CP server 300, the RCS agent 210 may transmit the message to the bot service 230. The RCS agent 210 may access the bot registry 220 to obtain information about the CP server 300.

According to an embodiment, the bot registry 220 may store detailed information about the CP servers 300. For example, the detailed information may include the name, address, phone number, service types provided, or other property information of the dialog content providing service (or CP server). The bot registry 220 may be a module that stores the corresponding information when the developer of the dialog content providing service registers the service related information (e.g., chatbot information). The bot registry 220 may respond to the search and information request associated with the dialog content providing service from the electronic device 100. The bot registry 220 may process information request associated with the dialog content providing service from the RCS agent 210 or the bot service 230.

According to an embodiment, the bot service 230 acts as a relay between the electronic device 100 and the CP server 300. The bot service 230 can be a module that communicates with the CP servers 300 for the dialog content providing service. The bot service 230 may make a request for information associated with the dialog content providing service to the bot registry 220 and may transmit the message obtained from the CP server 300 to the RCS agent 210 to allow the RCS agent 210 to transmit the message to the electronic device 100. The bot service 230 may transmit the message obtained from the RCS agent 210 to the CP server 300. The bot service 230 may convert source and destination information obtained from the RCS agent 210, to information of a format capable of accessing the CP server 300. On the other hand, the bot service 230 may change the format of the source and destination information obtained from the CP server 300 such that the RCS agent 210 is capable of communicating with the electronic device 100.

The RCS network 10 may comply with the RCS (an example of first protocol) that is the international standard protocol for the next generation integrated message service. The RCS may be an international standard for the next generation integrated message service adopted by the Global System for Mobile Communications Association (GSMA) and may provide various services (e.g., group chat, file transmission, state check of the recipient, message transmission state check, or the like) that are not provided by the conventional message service.

According to an embodiment, the RCS network 10 may be operated by an MNO and may specify subscribers (e.g., the electronic device 100 or the CP servers 300) based on at least a phone number (e.g., mobile station international subscriber directory number (MSISDN)).

According to an embodiment, unlike an OTT-based message application (e.g., Facebook Messenger™, Line™, Kakaotalk™, What's app™, or the like), a message application program (hereinafter, an application) using the RCS network 10 may be implemented with a native application. Accordingly, the user does not need to additionally and separately download or install a message application to use the RCS network 10 and may be provided by the electronic device 100. In addition, since utilizing a phone number to specify a subscriber, a message application using the RCS network 10 might not require the user to sign up or log in (or sign in).

According to an embodiment, for example, the CP servers 300 (310, 320, and 330) may be developed by each content provider (CP). The CP server 300 may provide an initial response message (so-called, welcome message), or a message associated with a service provided by the CP server 300, to the electronic device 100 through the platform server 200 and the RCS network 10.

According to an embodiment, the CP servers 300 may include a natural language processing (NLP) module (or a natural language understanding (NLU) module) that supports machine learning or artificial intelligence. The NLP module may derive the meaning of the natural language or the context included in the message received from the electronic device 100 and may automatically generate a message corresponding to the meaning or the context.

According to an embodiment, the CP servers 300 may implement a chatbot providing the dialog content providing service. For example, each of the CP servers 300 may implement one chatbot or may implement a plurality of chatbots. Hereinafter, for convenience of description, various embodiments will be described based on the fact that one CP server 300 correspond to one chatbot. In the present disclosure, the CP servers 300 may be referred to as a “chatbot 300” or “bot 300”.

According to an embodiment, the chatbots 300 may transmit a message or content to the electronic device 100 through the platform server 200. The message generated by the chatbots 300 may comply with a second protocol different from the RCS. For example, the message generated by the chatbots 300 may comply with HTTP.

According to an embodiment, the electronic device 100, the user of the electronic device 100, or the platform server 200 may identify the chatbot 300 based on at least an RCS identifier. The same RCS identifier may be assigned to the chatbots 300 or different RCS identifiers may be assigned to the chatbots 300. According to an embodiment, the RCS identifier may have the form of the phone number (e.g., MSISDN) of a chatbot or URI.

According to an embodiment, the chatbots 300 sharing the same RCS identifier may be identified based on an additional identifier. For example, the additional identifier may be used to identify the chatbots 300 in the electronic device 100 and/or the platform server 200. According to an embodiment, the additional identifier may be a unique identifier (ID) of the chatbot or the extension of the RCS identifier.

According to an embodiment, the chatbot 300 may have its own location on the data network, and the chatbot 300 may have the location identifier or location information for communication with the platform server 200. For example, the location identifier may be a uniform resource identifier (URI) or a uniform resource locator (URL).

In operation 709 a, the RCS agent 210 may transmit the first message to the bot service 230. Operation 709 a may be the same as or similar to operation 409 of FIG. 4.

In the case where the bot ID is provided, the electronic device 100 may perform operation 705 b and operation 709 b for the purpose of transmitting the first message. For the purpose of distinguishing operation 705 a to operation 709 a from operation 705 b and operation 709 b, the electronic device 100 may determine whether the bot ID of the chatbot is provided.

In operation 705 b, the electronic device 100 may transmit the bot ID of the chatbot 310 together with a phone number of the chatbot 310. In operation 705 b, while transmitting the first message to the RCS agent 210, the electronic device 100 may include destination information and source information in the first message. The destination information may include the phone number and the bot ID of the chatbot 310. The source information may include the phone number of the electronic device 100.

Since the RCS agent 210 has received the bot ID from the electronic device 100, in operation 709 b, the RCS agent 210 may transmit the first message to the bot service 230. The RCS agent 210 may use the bot ID obtained from the electronic device 100 instead of obtaining the bot ID from the bot registry 220. The destination of the first message transmitted to the bot service 230 may be the bot ID, and the source may be a user phone number.

In operation 711, the bot service 230 may store a user ID. Operation 711 may be the same as or similar to operation 411 of FIG. 4.

In operation 713, the bot service 230 may obtain chatbot URL. Operation 713 may be the same as or similar to operation 413 of FIG. 4.

In operation 715, the bot service 230 may transmit the first message to the chatbot URL. In certain embodiments, operation 715 can include transmission of a message formatted as shown in Tables 7 and 8. Operation 715 may be the same as or similar to operation 415 of FIG. 4.

According to an embodiment, the chatbot 310 may transmit a second message to the electronic device 100 in response to the first message. In operation 717, the chatbot 310 may transmit a second message to the BOT service 230 in response to the first message. In certain embodiments, operation 717 can include transmission of a message formatted as shown in Tables 9, 10, and 11. Operation 717 may be the same as or similar to operation 417 of FIG. 4.

In operation 719, the bot service 230 may obtain user MSISDN. Operation 719 of FIG. 7 may be the same as or similar to operation 419 of FIG. 4.

In operation 721, the bot service 230 may transmit the second message to the RCS agent 210. The destination of the second message may be the user MSISDN, and the source may be the bot ID. Operation 721 may be the same as or similar to operation 421 of FIG. 4.

In operation 723, the RCS agent 210 may transmit the second message to the electronic device 100. The RCS agent 210 may include chatbot MSISDN and the bot ID in the source information. The electronic device 100 may identify the source of the second message based on the chatbot MSISDN and the bot ID. According to various embodiments, the electronic device 100 may display the second message in a chatroom corresponding to the source of the second message.

At least part of operations illustrated in FIG. 7 may be variously changed according to various embodiments of the present disclosure. For example, transmission of the bot ID in operation 705 b may be performed independently of the transmission of the connection request. The connection request may include only the chatbot MSISDN as destination information.

FIG. 8 is a flowchart of a method in which an electronic device and a chatbot transmits and/or receives a message through a platform server, according to an embodiment.

Referring to FIG. 8, the electronic device 100 (e.g., the electronic device 100 or processor 102 of FIG. 2) and a chatbot (e.g., the chatbot 310 of FIG. 1A) may verify the existence of each other by using at least phone number extension. According to an embodiment, the chatbot may share the same phone number with another chatbot. The extension of a phone number as well as a phone number may be used for distinction between chatbots. In the case where the electronic device 100 transmits a message, the electronic device 100 may transmit the extension together and the bot service 230 may identify a bot ID based on the extension. The extension may be an additional identifier of the chatbot.

A platform server (e.g., the platform server 200) according to an embodiment may include the RCS agent 210, the bot registry 220, and/or the bot service 230.

In the following description of FIG. 8, the RCS identifier of the chatbot may be chatbot MSISDN, the unique identifier of the chatbot may be a bot ID, and the location identifier of the chatbot may be a chatbot URL. In the following description of FIG. 8, the RCS identifier of the user (or an electronic device) may be user MSISDN, and the unique identifier of the user (or an electronic device) may be a user ID.

In operation 801, the electronic device 100 may search for a chatbot in the bot registry 220. In certain embodiments, operation 801 can include transmitting a message formatted as shown in Tables 1 and 2. Since operation 801 is the same as or similar to operation 401 of FIG. 4, a detailed description thereof is thus omitted.

In operation 803, the bot registry 220 may transmit the found result to the electronic device 100. In certain embodiments, operation 803 can include transmitting a message formatted as shown in Tables 3 and 4. Operation 803 may be the same as or similar to operation 403 of FIG. 4.

Referring to FIG. 8, in operation 805, the electronic device 100 may transmit the chatbot MSISDN and the extension of the chatbot 310 together, when transmitting a first message. For example, the destination information of the connection request may include the chatbot MSISDN and the extension of the chatbot 310, and the source information may include user MSISDN.

In operation 807, the RCS agent 210 (e.g., the RCS agent 210 of FIG. 1A) may transmit the first message to the bot service 230 (e.g., the bot service 230 of FIG. 1A). For example, when transmitting the first message, the RCS agent 210 may set the destination of the first message to the chatbot MSISDN and the extension, and may set the source to user MSISDN.

In operation 809, the bot service 230 may obtain a bot ID. For example, the bot service 230 may obtain the bot ID based on at least the extension.

In operation 811, the bot service 230 may store a user ID. The bot service 230 may obtain the user ID based on the user MSISDN. According to an embodiment, when storing the user ID, the bot service 230 may map the user ID to the phone number. In the case where the bot service 230 receives a second message as a response to the first message, the bot service 230 may use the user ID stored to obtain the user MSISDN. The user ID may be used for the purpose of protecting the privacy of the user. When using the user ID, even though the bot service 230 does not notify the chatbot 310 of the user MSISDN, it is possible to exchange information between the user and the chatbot 310.

In operation 813, the bot service 230 may make a request for the chatbot URL of the chatbot 310 to the bot registry 220, and may obtain the chatbot URL from the bot registry 220. Operation 813 may be the same as or similar to operation 413 of FIG. 4.

In operation 815, the bot service 230 may transmit the first message to the chatbot 310; in operation 817, the bot service 230 may obtain the second message as a response to the first message. According to an embodiment, the source of the second message may be the chatbot 310, and the destination thereof may be the electronic device 100. The second message may include the bot ID as the source and may include the user ID as the destination. Operation 815 may be the same as or similar to operation 415 of FIG. 4, and operation 817 may be the same as or similar to operation 417 of FIG. 4.

In operation 819, the bot service 230 may obtain a pair of the chatbot MSISDN and the extension of the chatbot 310, based on the user ID included in the second message. According to an embodiment, the bot ID may be mapped to the pair of the chatbot MSISDN and the extension.

In operation 821, the bot service 230 may obtain user MSISDN. According to an embodiment, the bot service 230 may obtain the second message from the chatbot 300 and may obtain the user MSISDN based on the user ID included in the second message. The bot service 230 may convert the destination of the second message into the user MSISDN and may convert the source of the second message to the chatbot MSISDN and the extension.

In operation 823, the bot service 230 may transmit the second message to the RCS agent 210. When transmitting the second message, the bot service 230 may include the user MSISDN instead of the user ID as the destination information in the second message. When transmitting the second message, the bot service 230 may include the chatbot MSISDN and the extension instead of the bot ID as the source of the second message.

In operation 825, the RCS agent 210 may transmit the second message to the electronic device 100. The destination of the second message may be the user MSISDN. The electronic device 100 may verify that the second message is associated with the electronic device 100, based on the user MSISDN. The RCS agent 210 may include the chatbot MSISDN and the extension as the source information in the second message. The electronic device 100 may determine the chatroom for displaying the second message, based on the source information of the second message.

As described above, when the chatbot phone number is shared with a plurality of chatbots (e.g., the chatbot 310 and the chatbot 320 of FIG. 1A) and the phone number is displayed in a user interface, it is difficult for the user to distinguish the phone number of the chatbots. Moreover, when the user selects one chatbot phone number, an electronic device (e.g., the electronic device 100 of FIG. 1A) and a platform server (e.g., the platform server 200, the RCS agent 210, or the bot service 230 of FIG. 1A) may not determine which chatbot is the message from the user associated with?

According to an embodiment, the electronic device 100 may display the chatbot phone number and the extension associated with the chatbot in a user interface. According to an embodiment, the electronic device 100 may display the extension associated with the chatbot after the chatbot phone number.

When displaying the extension, the electronic device 100 may display symbol “PAUSE” or symbol “WAIT” in the phone number. According to an embodiment, the electronic device 100 may display the chatbot phone number by using character “p” or “w” or symbol “,” or “;”. For example, in the case where the phone number of the first chatbot (e.g., the first chatbot 310 of FIG. 1A) is set to “821234567” and the extension set to “12345”, the phone number of the first chatbot such as “+821234567p 12345”, “+821234567w 12345”, “+821234567, 12345”, or “+821234567; 12345” may be displayed in the user interface.

That the electronic device 100 displays the extension may mean that when a call is connected, the electronic device 100 transmits the extension after the corresponding symbols (e.g., p, w, or the like) with dual tone multi frequency (DTMF) such that a separate extension is capable of being connected. In this case, the user may naturally connect the call to the person in charge, while talking with the chatbot.

Hereinafter, a method of transmitting an additional identifier in addition to a phone number will be described. According to an embodiment, the additional identifier may be at least one of a unique identifier (e.g., bot ID) or the extension of a phone number. Hereinafter, a method in which an electronic device (e.g., the electronic device 100 of FIG. 1A or the electronic device 100 of FIG. 2) transmits the additional identifier will be described based on the case where the additional identifier is the bot ID.

According to an embodiment, an electronic device may include bot ID information in an RCS message. According to an embodiment, the RCS message format may include a header, and the bot ID information may be included in the header.

The bot ID information according to an embodiment may be included in a session initiation protocol (SIP) message. For example, the bot ID information may be included in a SIP header. Returning to FIG. 7, in operation 705 b, a connection request may be the SIP message, and the bot ID information may be included in the header of the SIP message.

The SIP header may be used when a chat session is generated; after the chat session is established, messages may be transmitted and/or received within a session established without the help of the SIP message. Accordingly, in the case where an electronic device transmits an identifier by using a SIP header when talking with a plurality of chatbots having the same phone number, an electronic device needs to use a separate session for the purpose of talking with each chatbot.

According to an embodiment, while one electronic device talks with chatbots sharing the same phone number with each other in different chat threads, one electronic device may exchange a chat with a plurality of chatbots by using one chat session. According to an embodiment, the electronic device may include bot ID information in a common profile for instant messaging (CPIM) message. For example, the bot ID information may be included in the CPIM header. When using the CPIM header, the electronic device may transmit a message by using the bot ID after a session is connected. Accordingly, when talking with chatbots having the same phone number, the electronic device may use one session. However, in the case where one user is invited in a group chat, the bot ID information may be included in a SIP header of a REFER message or the like.

When the session is connected, the electronic device may transmit a message (or chat) wrapped with CPIM by using a message session relay protocol (MSRP). Herein, the electronic device may transmit the receiving-side bot ID using an additional parameter.

According to an embodiment, the RCS message may include payload, and the bot ID information may be included in the payload of the message. Alternatively, the bot ID information may be transmitted before the payload is transmitted, and the destination of the payload may be specified.

According to an embodiment, chat parties, for example, the chatbot and the electronic device may be divided into two types depending on whether the source and destination includes the additional identifier. One may be a first type in which the source and destination does not include the additional identifier, and the other may be a second type in which the source and destination includes the additional identifier. The first type may include a chatbot or an electronic device, and the second type may include a chatbot. For example, the additional identifier may be the extension. In the following description, the additional identifier may be the extension.

In the case where the first type and the second type coexist in a plurality of sources and destinations, when the extension is used in addition to a phone number, there are a variety of scenarios between an electronic device and a chatbot or between a chatbot and another chatbot.

-   -   (a) Chat between first types     -   (b) 1:1 Chat between the first type and the second type     -   (c) 1:1 Chat between second types ((1) in the case where phone         numbers are different from each other, (2) in the case where         phone numbers are the same as each other)     -   (d) Group chat in which only the first type participates     -   (e) Group chat in which only the second type participates ((1)         in the case where all phone numbers of the second types are         different from each other, (2) in the case where there are two         or more participants, each of which has the same phone number,         in the second types)

Various embodiments of the present disclosure may be identically applied to the variety of scenarios or may be applied to the variety of scenarios after being changed.

In the case of (a), when a chat between the first type devices is performed, an independent chat session is established between the first type devices, and the independent chat thread may be opened. The source and destination information may be included in the SIP header or the CPIM header.

In the case of (b), the source and destination (e.g., an electronic device or a chatbot) of one first type may do 1:1 chat with a plurality of second type sources and destinations (e.g., chatbot) different from each other. In the case of a 1:1 chat, a platform server or an electronic device may not generate a plurality of chat sessions for each of second type chatbots and may share the chat session with each other. For example, in the case where the second type chatbots use the same phone number, the platform server may make it possible to share one chat session.

According to an embodiment, in the case where the electronic device chats with each of the plurality of second type chatbots, the electronic device may include extension information in the CPIM header upon transmitting a message. Alternatively, when the electronic device receives a message, the extension information may be included in a CPIM header. Since a chat may be transmitted and/or received within a session established without the help of the SIP message after the chat session is established, the electronic device may use the CPIM header without using the SIP header when transmitting the extension information.

In the case of (1) (in the case where phone numbers between second types are different from each other during a chat between second types) of (c), source and destination information may be included in the SIP header or the CPIM header. Since different phone numbers are used, an independent chat session may be established between second type devices, and the independent chat thread may be opened.

According to an embodiment, a chat between second types may be a chat between chatbots. In this case, chatbots may exchange a chat through an RCS network. Alternatively, a chat between chatbots may be routed within a server without passing through the RCS network.

In the case of (2) (in the case where phone numbers between second types are the same as each other, during a chat between second types) of (c), a dialog content providing system may operate as follows.

According to an embodiment, in the case where the phone numbers between second types are the same as each other, the same chat session may be shared. At this time, a chat may be performed through different chat threads among second types. In this case, the phone number may be included in the SIP header, and the extension may be included in the CPIM header for a distinction between second types.

According to an embodiment, a chat between second types may be a chat between chatbots. In this case, chatbots may exchange a chat through the RCS network. Alternatively, a chat between chatbots may be routed within a server without passing through the RCS network.

In the case of (d), since only the first type participates, participants may include different phone numbers, respectively. In this case, a separate chat session may be opened with respect to each of the participants.

In the case of (1) of (e), one chat thread may be established between second types having different phone numbers, and a separate chat session may be established with respect to each of the participants.

In the case of (2) of (e) (in the case where there are two or more participants, which have the same phone number, in second types, during a group chat in which the second type participates), a separate chat session may be established or a chat session may be shared. From the perspective of a conference focus hosting group chat, the conference focus may establish a separate chat session (hereinafter referred to as a “one-to-one chat session”) with a second type destination having the same phone number, or may establish one chat session (hereinafter referred to as a many-to-one chat session) with all the second type destinations having the same phone number. In the case of a many-to-one chat session, a chat may be transmitted to the chatbots corresponding to each extension by the platform server that is the destination side.

In a many-to-one chat session, after a chat session between conference focus and an electronic device is connected, the source and destination may be distinguishable between the conference focus and the electronic device without the help of the SIP message. Accordingly, the electronic device or the server may transmit the extension by using the CPIM header.

In the RCS standard, an event of Disposition and IsComposing may be defined. In the case of Disposition event, it is defined that the electronic device uses the SIP header and the CPIM header during a general chat. Even in the case of a chat with a chatbot, the electronic device may use the SIP header and the CPIM header.

In the case of IsComposing event associated with a 1:1 chat, the RCS standard specifies that netwrok (e.g., RCS network) does not use the CPIM header. However, in an embodiment of the present disclosure, as described above, network may use the CPIM header because network does not use the SIP header in a chat between the first type and the second type.

According to an embodiment, in the case of a group chat, when a group chat is started and when a participant is changed during the group chat, a participant list may be exchanged among the electronic device, the server, and/or the chatbot. According to an embodiment, the participant list may be referred to as a “resource list”. According to an embodiment, the resource list may be represented as resource list xml. The extension of the participant included in the participant list may be displayed in the resource list.
